Description
Vulnerability in the Oracle SOA Suite product of Oracle Fusion Middleware (component: Fabric Layer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via T3, IIOP to compromise Oracle SOA Suite. While the vulnerability is in Oracle SOA Suite, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle SOA Suite. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

AI Analysis

Impact

The vulnerability, an access control weakness (CWE-284), resides in the Fabric Layer component of Oracle SOA Suite, permitting an unauthenticated attacker with network access to the T3 or IIOP protocols to take full control of the system. The flaw effectively allows compromise of confidentiality, integrity, and availability, and the vulnerability was classified with a CVSS 3.1 Base Score of 10.0, indicating successful exploitation results in a complete takeover of the Oracle SOA Suite services.

Affected Systems

Oracle SOA Suite versions 12.2.1.4.0 and 14.1.2.0.0 are impacted. The issue may also affect other Oracle Fusion Middleware products, as the scope can change beyond the immediately mentioned product. Administrators should verify that these specific releases are in use and consider the potential impact on associated components.

Risk and Exploitability

The attack vector is network-based, requiring only unauthenticated access to T3 or IIOP endpoints. Because the vulnerability is easy to exploit and no additional privileges are needed, the risk is high. The high CVSS score combined with the lack of constraints on exploitation suggests that an attacker could immediately gain control if the system remains unpatched. The EPSS score is < 1%, indicating a very low but nonzero probability of active exploitation. The vulnerability is not currently listed in CISA's KEV catalog; however, the severity and ease of exploitation warrant priority remediation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Oracle software update from the CPU Oct 2026 security advisory for versions 12.2.1.4.0 and 14.1.2.0.0 of Oracle SOA Suite.
  • If an immediate patch cannot be applied, block inbound traffic to the T3 (TCP 6001) and IIOP (TCP 7001) ports from untrusted networks or restrict access to a trusted internal network segment as a temporary workaround.
  • Enable logging and continuously monitor T3 and IIOP activity for anomalous authentication attempts or suspicious traffic, and review audit logs for signs of exploitation.
